Finding causality is hard and this study has so many hidden confounders that even implying causality from weed to anxiety disorder is bullshit.
Anecdotally, the only people I know that ended up in ED due to weed either took it unknowingly or have Cannabinoid hyperemesis syndrome from heavy heavy usage. Surely someone with a tendency for anxiety is more likely to seek medical help.
I know cannabis smokers who have anxiety issues, but it isn't obvious whether their tendency for anxiety leads them to smoking. I'm ignoring temporary anxiety. Disclosure: not a pot smoker.
